Abstract

A motor vehicle seat with an integrated child seat, the child seat comprising inflatable chambers that can be brought from a compressed The child seat includes air chambers that are inflatable in multiple, e.g., three, stages, and which are fixed, e.g., adhesively bonded or stitched, to the surface of the motor vehicle seat.

Claims

1-8. (canceled)

9. A motor vehicle seat comprising an integrated child seat, the child seat comprising: inflatable chambers transformable from a compressed undeployed state into an inflated deployed state by a compressed air source, wherein the chambers are inflatable in multiple stages, and are fixed to a surface of the motor vehicle seat.

10. The motor vehicle seat of claim 9, wherein the air chambers are cross-linked.

11. The motor vehicle seat of claim 10, wherein the chambers are cross-linked by Kevlar yarns.

12. The motor vehicle seat of claim 9, wherein individual air chambers are provided for the seat surface, head restraint and side ribs.

13. The motor vehicle seat of claim 9, wherein at least one of the head restraint or backrest are adjustable by motor.

14. The motor vehicle seat of claim 9, wherein the stages are superimposed on one another.

15. The motor vehicle seat of claim 9, further comprising a controller, a multi-way valve, and a compressed air source, such that the controller can act in a targeted manner on the air chambers via the valve from the compressed air source.

16. The motor vehicle seat of claim 15, wherein the multi-way valve is a three-way valve.

17. The motor vehicle seat of claim 15, further comprising weight and height sensors connected to the controller.

18. The motor vehicle seat of claim 9, further comprising a seat belt guide which is adjustable by motor.

19. The motor vehicle seat of claim 9, wherein the chambers are inflatable in three stages.

20. The motor vehicle seat of claim 9, wherein the chambers are adhesively bonded or stitched to the surface of the motor vehicle seat.

21. A motor vehicle seat comprising an integrated child seat, the child seat comprising: inflation means for inflating inflatable chambers transformable from a compressed undeployed state into an inflated deployed state; fixing means for fixing the chambers to a surface of the motor vehicle seat; and stage means for inflating the chambers in multiple stages.

Description

[0017] Further features and details of the invention are disclosed from the following description of the drawings, in which:

[0018] FIG. 1 shows a plan view of a motor vehicle seat with an integrated child seat;

[0019] FIG. 2 shows a side view of the motor vehicle seat of FIG. 1; and

[0020] FIG. 3 shows a sectional view through the woven fabric in the region X of FIG. 2.

[0021] A motor vehicle seat with an integrated child seat denoted as a whole by 1 is shown in the figures.

[0022] The motor vehicle seat 1 comprises a seat surface 2, a backrest adjacent thereto 3 and a head restraint 4.

[0023] The seat surface 2 is additionally provided with lateral ribs for the side support.

[0024] A second skin, and also a third skin thereabove, are stitched onto the surface of the seat cover at suitable points 5, 6, 7 in order to configure the integrated child seat.

[0025] This forms air chambers which are inflatable in three stages A, B, C and which are inflatable from inside to outside in order to adapt the size of the child seat.

[0026] The seat height and the side support are adjusted by the chambers 5A, B, C.

[0027] The side support of the torso and the backrest length are adjusted via the backrest chambers 6A, B, C. To this end, the backrest 3 is additionally adjustable in height by motor.

[0028] The side support of the head and the upper body length of the child are adjusted by the head restraint chambers 7A, B, C. To this end, the head restraint 4 is additionally adjustable in height by motor.

[0029] Thus a plurality of adjustment stages are produced for children of different sizes, as is indicated with reference to the arrows in FIG. 2.

[0030] The woven fabric 8 of the chambers 5, 6, 7 includes three layers A, B, C connected together, wherein the intermediate space in each case forms one of the stages (see FIG. 3).

[0031] Each chamber can be subjected in a targeted manner to compressed air from the compressed air source 12 (compressor, etc.) via a three-way valve 9.

[0032] To this end a controller 10 is provided, the valve 9, the compressed air source 12 and the motorized drives for the backrest 3 and the head restraint 4 being activated thereby.

[0033] Additionally, weight and height sensors 11 are arranged in the seat surface and the backrest and/or head restraint, said sensors also being interconnected with the controller 10, so that when the seat is occupied by a child this controller is able to inflate the chambers 5, 6, 7 including the required layers A, B, C automatically and is able to move the backrest 3 and the head restraint 4 in an appropriate manner, wherein with the adaptation of the head restraint 4 a seat belt guide 13 which has been released at that point is also adjusted in terms of height.
